The dangerous you're talking about have been around for a long time, have been depicted in many forms over decades in all kinds of popular media media, have actually impacted people which has birthed reforms and new safety measures, and that is all part of the constant education and training the public receives.
None of that is done for FSD or tesla cars. People don't know how they work, what the dangers are, what their failure modes are, how to approach them, and no one is telling them!
If you want to lament a general lack of awareness and progressive education, then I'm fully on board. Perhaps we should require operators to pass an additional driver test to be legally permitted to supervise any L2+ system from any manufacturer. No BlueCruise or SuperCruise unless you've got the extra marking on your license.
But as far as "consent" is concerned, if you wish to use the public roads, consent necessarily means accepting the roads as a commons. This means, at minimum, accepting the presence of anything the relevant government authority deems legal.
